This replacement bump-feed button mounts at the bottom of a string trimmer head and operates the line-advance mechanism. Tapping the trimmer head lightly against the ground during use allows additional cutting line to feed from the spool without stopping for a manual adjustment. Replace the button if it is worn, cracked, missing, or no longer responds when tapped. This component replaces the bump button rather than the complete trimmer head. Remove the battery before installation and verify fit before ordering.
